With a pretty crazy live Google+ stream from skydivers wearing Project Glass, Sergey Brin introduced Project Glass. We've already heard some of the details, including the presence of an onboard camera, sensors (gyro, accelerometer, compass), onboard radios, and so forth. Project Glass has two goals - sharing imagery, and getting rapid access to information. Capturing imagery through the point of view of the user is part of that first goal, along with scenes and parts of life that wouldn't normally be accessible with a traditional camera.

Today, Google is announcing Glass Explorer Edition, which is available for preorder at Google I/O for US based attendees for $1500, with shipping early next year. This is not a consumer electronic but intended to start development of applications for Project Glass. Sergey mentioned that the device will not be perfect and might be occasionally rough, but this is the very first time anyone will get to play with Google Glass.
